It has Teflon POWDER and crazy-glue adhesive. NEVER, I repeat NEVER use Teflon tape. Ordinary pipe dope is fine. The thread lockers do not affect the fiber or plastic lock rings on self-locking nuts. Blue grade Loctite is fine. Red is a little tougher and is sometimes referred to a bushing and bearing locker. It requires heat to remove. If it isn't in the plans, you are adding un-necessary weight which degrades flight performance. If you want to make changes, ask the factory or designer.

Looking a few pages ahead to the installation of the fuel tank I see I'm gonna need to buy a few more items I don't have yet,such as a flycutter. I know where to get a flycutter but can anyone tell me where to get the following: > 1.

I know about locktite but it might melt the nylon in the nut? Is there something else that is used for aircraft bolts?

What is this stuff and can i order it from AC Spruce? Larry, What you want to use on your fuel fittings is called Fuelube. It's available at AC Spruce, P/N 09-25300, page 318 of the ACS catalog.

Since the fuel systems of all the cars, trucks and buses in North America are not filled with Teflon threads, one has to conclude the product works very well. The idea that it's too difficult to use correctly is, of course, incorrect!

The big problem is not its use, but it re-use. If the Teflon tape is not carefully removed from the first use, when the fitting is removed and then re-installed, the operation of re-installing can create a problem. The action of using re-installing pushes the little bits of tape into the line where it is free to move until it is hopefully stopped by a filter. This is what happens in the car system. The filters in the stop these little bits from getting to the carb or fuel injectors. When using it an airplane, it might go down stream from a fitting to the main jet or the small screen at the carb inlet. This can have disastrous results. You can't just coast over the side of the road in an airplane and wait for the tow truck. Tape use on oil lines can have the same effect. If you read the instruction on the box for a vacuum pump, using tape voids the warrantee. As Teflon pipe drop is really available and work very well, I don't see why anyone would insist on using the tape with its possible problems.
